Abstract

The invention discloses an additive of laying hen feed for replacing antibiotic and application and a method thereof. The additive of laying hen feed for replacing antibiotic comprises a Chinese herbal medicine composition and a yeast culture; the Chinese herbal medicine composition comprises elsholtzia, bighead atractylodes rhizome and pomegranate rind, and the yeast culture comprises yeast viable count greater than or equal to 2 * 10 < 11 > cfu/kg, protease activity greater than or equal to 2 * 10 < 5 > u/kg and moisture less than or equal to 12%; the weight ratio of the Chinese herbal medicine composition to the yeast culture is 1: (75-125). The additive of laying hen feed for replacing antibiotic can improve the egg laying performance of laying hens, improve the egg quality, increase the visceral organ index of the laying hens, enhance the immunity of the laying hens, improve the antioxidant capacity of the laying hens and perfect the intestinal morphology of the laying hens, is wide in raw material source, low in price and not prone to generating drug resistance, and can be used as a substitute of antibiotics to be applied to the field of feed additives.

Description

technical field [0001] The invention relates to the technical field of poultry feed additives, in particular to an antibiotic feed additive for laying hens and its application and method. Background technique [0002] Antibiotics were once widely used as feed additives for livestock and poultry, meeting the needs of disease prevention, treatment of infection and promotion of animal growth in large-scale farming, but due to the bacterial resistance caused by antibiotics, the safety of livestock products and human health The public's acceptance of antibiotics in farming is declining, and the health and safety of antibiotic feed additives have become the focus of attention at home and abroad. At present, in the implementation of the "comprehensive ban on antibiotics" policy in my country's feed industry, it is urgent to develop healthy and efficient alternative antibiotic additives. [0003] Safe and efficient non-antibiotic additives should meet the requirements of not threat...
